MIXING AND PROPORTIONING VALVE.

Specification of Iietters Patent.

Application filed January 8, 1913. Serial No. 740,884.

To all whom it may concern:

Be it known that 1, CHARLES E. LUCKE, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Mixscribedand represented in the following specification and the accompanyingdrawings, forming a part of the same.

My invention relates to valves, and more particularly to a type-ofmixing valves.

The main object of the invention is to provide a valve .wherebydissimilar fluids may be drawn and mixed in any desired volume up to thecapacity of the valve, and

whereby the proportion of one fluid entering into the mixture relativeto that of the other may be controlled independently of the volumeadjustment.

A further object is to provide a valve wherein the volume andproportionate quantity adjustments may both be secured by means of asingle valve block or plug.

A still further object is to provide a valve which may be set to securea desired mixture and may thereafter be operated to secure a varyingvolume of the mixture, without varying the proportions of the fluidsentering thereinto.

A still further object is to provide a valve wherein the block or plugwill automatically take up wear thereon so as to always find a perfectseat. And a still further object is to provide a valve which will besimple in design and may be readily and quickly adjusted to meetchanging conditions of use.

The invention consists primarily in a valve embodying therein a valveseat forming means having a plurality of intake ports therein, a valveblock seated against said seat, said valve block beingported toestablish communication between said intake ports and an ofi'take, andindependently operative means whereby said intake ports may besimultaneously and proportionately opened and said valve may be adjustedtovary the relative capacity of said mg and Proportioning Valves, fullyde-' ing, showing the arrangement of the ports therein; Fig. 5 is a viewsimilar to Fig. l, but of a modified form of valve, the valve beingshown closed; Fig. 6 is a view similar to Fig. 5 showing the valveadjusted for different proportion, and fully open; and Fig. 7 is asection on the line 77 of Fig. 5.

In the forms of the invention shown, I employ a casing 10 having acylindrical bore and providing the valve seat and having therein aplurality of intake ports 11 and 12 and an oiftake port 13, preferablyalined with and intermediate said intake ports. Seated in this casing isa valve block or' plug 14: having a close working fit with the borethereof, and provided with a port or channel as 15 adapted tosimultaneously register, or communicate, with the intake ports 11 and 12and the oft'take port 13. The plug may be turned for opening and closingthe valve by a handle 16 or other operating means. When a valve of thischaracter is used for forming an explosive mixture of a fuel gas'andair, the port 11 for gas will have less capacity than the port 12 forair. In order to have both ports open simultaneously and proportionatelyfor all proportion adjustments, they are, in the form of valve shown,made rectangular, one dimension thereof, that in the direction ofmovement of the plug for opening and closing the ports, being the same,and the other dimension thereof, that axially of the casing 10,differing according to the desired maximum capacity of said ports. Thisconstruction permits the simultaneous opening of both valves and agradual uniform pro- X f construction, the block is made up ofa mainpart 25 which is. recessed or cut away on portionate increase in thecapacity of the ports-with continued movement of the valve -block. Bymeans of these ports and said valveblock, the valve may be adjusted forvolume only,lto:secure a desired quantity of communicate with the intake"ports ll and 12 respectively, and communicating with the 'oiftake port13 is the ofl'take or deliverypipe 19 which -for convenience is arrangedupon the side of the l casing opposite to that from which the pipes 17and 18 lead, the said ofitake lead being in communication with the port13 1 through a channel 20 formed in said casing I of the two gasespriorto their discharge and encircling the block or plug 14; By

having this channel completely encircle the plug, therdesired capacitymay be secured with asmaller channel than would otherwise berequired'and abetter commingling into the lead 19 issecured. Thisconstruction, however,is largely a matter of convem'ence, andthealead 19may be connected with the ofitake port in any desired manner.'

To permit an adjustment of the valve in a manner to vary the,proportions of the gas and air or other dissimilar fluids entering intothe mixture, .I provide means whereby I the valve may be so adjusted asto vary the relative capacity of the intake ports.

order to secure such an adjustment without,

loss ofthe simultaneous opening and proportionate adjustment for'volumewith any desired adjustment for proportions, I provide means whereby therelativeeflective dimensions of the ports 11 and 12 axially of thecasing 10 may be varied. Preferably I utilize the valve .block or plug14 for acwise: within the casing; This screw operates ass own. I y Inthe forinfof the invention shown in 1 Figs. 1 to 4: ofithedrawings'inclusive, I [showa rotary block which is adapted toautomatically "adjust itself to, compensate for a .complishing thisadjustment for proportions, providing means, as the screw 21 having anoperating handle 22 and lock nut 23,

for adjusting the position of the block end in screw, threads carried inthe head of the casing 10 and may be connected to the block or lug 14 bya suitable swivelconnection wear and form a gas tight joint. In this theside opposite the port 15, and a pressure piece or section 26 set'intherecess of the main part 25 and pressed outwardly against the Teasing bysprings, 27 seated in recesses'; formed in the part25. By thisconstruction,

the main part of the valve block which has the port 15 kept pressedagainst the caS-l closed and no flow of I occur. When it is desired toopen the valve,

inclusive, the construction is substantially I the same as that shown inthe preferred form, the principal difference being that a unitary rotarycylindrical block or plug 30 is used instead of the expanding blockshown in Figs. 1 to 4. The operation of both forms so far as theadjustment for volume and the adjustment for proportions is concerned,is identical. I The operation of the hereindescribed valve issubstantially as follows :--When the valve is shut ofl", the intake orts11 and 12 will be fluid therethrough will the plug or block 1a ismovedto simultanee ously open both of the ports 11 and 12, a

proportionate flow, determined by the capacities of these two ports,following. To 1 increase the volume of the flow, a continued openingmovement of the block or plug is all thatis necessary, the result beingmerely an increase of volume, the proportions of the two fluids passingthroughthe valve,

and which are mixed within thevalve in -the. constructions shown,remaining the prosame. If it be desired to change the portions of the"two fluids in the mixture, the

lock nut 23 is released and the adjustment f screw, 21 or its equivalentis actuated, thus varying the relative capacity of the outlet 1'00 ports11 or 12 and increasing the proportion of either fluid in the mixtureaccording'to the direction of movement imparted to the plug through thisscrew. Whenthe desired Q proportions in the mixture are secured, the

proportion adjusting device is set in its adjusted position, thusinsuring permanency in the proportions entering into the mixture, 7

without, however, interfering withthe adjustment for volume, suchadjustment, that 1-10 1 is, adjustment for volume,thenjresulting asbefore man increase or decrease of the volume without varying theproportions of the l fluids-entering into the mixture. --It will beobserved that in the valves shown the rotative block has a rotarymovement in ad The feed screw provides a simple means for accomplishingthe adjustment for proportions, by which exactness of adjustment issecured, and when the adjustment is once se- 7 cured, the adjustmentmeans may be locked inposition so as to avoid any variance in portions.

justingf or volume,- and an axial movement In the accompanying drawingsI have shown a form of valve which I prefer for accomplishing thisresult, but it is not my intention to limit my invention to the pre cisedetails of construction shown'in the drawings, as it is apparent thatsuch may be varied without sacrificing important advantages secured inthe form of the invention shown.
